This article deals with two new subclasses of analytic and bi-univalent functions in the open
unit disk, which is defined by applying subordination principle between analytic functions …

In this paper, two new subclasses of bi-univalent functions are introduced by using
generalized Bivariate Fibonacci polynomials. First, initial Taylor–Maclaurin coefficient …

The purpose of this article is to introduce a new subclass of analytic and bi-univalent
functions, in associated with sigmoid function and to investigate the upper bounds for| a (2) …

Abstract In 2010, Srivastava et al.[38] revived the study of coefficient problems for bi-
univalent functions. Due to the pioneering work of Srivastava et al.[38], there has been elicit …

In this work, we investigate some geometric properties of two subclasses of bi-univalent
functions defined by generalized Salagean differential operators related to shell-like curves …

In the present investigation, we define a subclass of bi-univalent functions related to shelllike
curves connected with Fibonacci numbers to find the estimates of second, third Taylor …
